Tico is a puzzle game a la Tetris in which you need to place the falling blocks in the playing area in a way to form lines and score points. There are multiple types of blocks with different shapes and colors, and you can see which block is coming next, so you can plan your moves ahead. The blocks can be rotated using the up arrow key, and you move them using the left and right arrow keys, and use down to drop the blocks more quickly.
The game offers two modes: Classic and Relax. The only difference between them is that in Relax mode, there is no score, so you play just for fun, the rest is exactly the same. You can also select the difficulty level by adjusting the bar, and allow counter rotation, if you want. The game offers very simple graphics and sounds, and no music. The background is always the same and the trial will only allow you to play for a couple of minutes.
To sum up, this is a very simple tetris game, which really doesn't have much to offer, so I suggest that you shouldn't waste your time and money on this one, when there are lots of better similar games out there.
